PUNCH.

SPECIFICATION forming part of Letters Patent No, 313,991, dated March1'7, 1885.

Application filed June 6, 18:'4. (No model.)

To all whom it may concern.'

Be it known that I, SOLOMON CoONs, of Orbisonia, in the county ofHuntingdon and State of Pennsylvania, have invented a new and ImprovedPunch, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved punch forpunching iron, steel, and other metals.

The invention consists'in the combination, with a block, of a die heldtoslide in the same, and a spindle provided with a head or nut having aspiral end surface adapted to act on the die, and aspiral groove, intowhich a prong or pin from a sliding bar passes, which sliding bar isconnected with the die, and is used to raise the same.

The invention also consists in parts and details and combinations of thesame, as will be fully set forth hereinafter.

Reference isto be had to the accompanying drawings, forming a part 'ofthis specification, in which similar letters of reference indicatecorresponding parts in both the igures.

Figure l is a longitudinal elevation of my improved punch, parts beingbroken out and others shown in section. Fig. 2 is a front end View ofthe same. Y l

A block or frame, A, is provided with two notches or recesses, B and C,between which a horizontal prong, D, is formed, in which the male die Eis held to slide vertically.

The dieE is provided on its lower end withv shoulders, offsets, orprojections a, which rest on the prongs of a fork, F, formed on thelowerend of a bar, G, held to slide in longitudinal grooves in the end of theblock, the forked end of the said bar being bent into the bottom recessor notch, C.

The sliding bar G is held in its grooves by a clip, H, held on the endof the prong D, and by a band or frame, J, surrounding the top of theblock, and provided with a binding-screw, J', for clamping the band onthe block, which screw acts on a key, J 2, held between the block andthe end cross-piece of the frame J The,

front cross-piece ot' the band or frame J is provided with a groove, G',for receiving a sliding guide-tongue, K, projecting upward from the barG.

A spindle, L, is held to turn in the end of the top prong, D', of theblock, and has a squared or other suitable head, L', on its upper end.

On the lower end of the spindle L a nut or head, M, is formed, which isprovided with a spiral groove, M', into which a prong, m, projects fromthe bar G. The bottom of the head M forms a spiral plane adapted to acton the rounded top E' of the male die E, which top projects more or lessfrom the bottom of the upper recess, B. The female die N is dove tailed,and slides into a dovetail groove in the bottom recess, C. l

A U-shaped frame,O,having slotted prongs, is held on the sides oftheprong D in such a manner that the cross-piece of the frame O passes overthe bottom of the recess C and over the die N, and as the prongs of theframe O are slotted the cross-piece of the frame O can be held a greateror less distance from the die N, as may be desired.

A longitudinal slotted gage-plate, P, having an upwardly-projecting lug,P', is held on one side of the block A, the top edge ot' the plate Pbeing liush with the bottom of the recess C. From the opposite side ofthe block a longitudinally-slotted bar, Q, projects, on which a movablegage, Q', is mounted, which can be locked in place by'means of a wingedscrew, R.

A key, S, having a rod, S', for turning it, is adapted to fit on thehead L.

The block A is provided with a handle, T, for holding it.

A block, \V, forming half of the box for the spindle L, is held on thefront or outer end ot' the prong D' by the frame J, and in the bot-- tomedge ofthe front of the block WV an antifriction roller, G2, is held, onwhich the top edge of the head M runs.

The operation is as follows: The piece of metal to be punched is placedon the female die N, and the spindle L is turned by means Y of the keyS, and the spiral plane on the bottom of the head M, acting on therounded top E', which may be an anti-friction ball, of the male die E,forces the said die downward and through the plate, &c., on the femaledie. lf the spindle L is then moved in the inverse direction, the bottomof the spiral groove M acts on the pin or prong m and pulls the bar Gupward, which in turn pulls the male die E upward. The cross-piece ofthe frame O IOO prevents the punched plate from rising with the die E,and thus the punched plate 'is pushed oft the die.

The punch can easily be held in any desired position. Itvoperatesrapidly, and comparatively little power is required to Work it.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Inapunch, the combination, with a block or frameand asliding die held in the saine, of a spindle provided with a headhaving a spiral end surface for acting on the end of the said spindle,and means for revolving` the said spindle, substantially as herein shownand described.

2. In a punch, the combinatioinwith a block or frame and a sliding dieheld in the saine, of 'a spindle having a spiral end surface, slidingbar operated by the spindle for raising the die, and means for operatingthe spindle, substantially as herein shown and described.

3. Inapunch, the combination, with a block 'or frame, of a sliding die,a spindle having a spiral groove, and also a spiral end surface adaptedto act on one end ofthe die, and a sliding rod connected with the dieand having a prong or pin projecting int-o the spiral groove in thespindle, substantially as herein shown and described. Y

4. In a punch. the combination, with the block or frame A, of thesliding die E, the spindle L, having a head or nut, M, provided with aspiral end surface, and the roller G2, against which the top of the nutM Works, substantially as herein shown and described.

5. In a punch. the combination, with the block or frame A, of thesliding die E, the spindle L, having a nut or head, M, provided F,holding the die E, and the prong m, projecting from the sliding bar Ginto the groove M, substantially as herein shown and described.

6. In a punch, the combination, with the block or fraineA, of thespindle L, a die adapted to be acted on by the spindle, the block XV,the band or frame J, and the screw J', substantially as herein shown anddescribed.

7. In a punch, the combination, with the block A, having recesses B C,forming a prong, D, of the die E, having the rounded top E', and fittedto slide freely in said prong, and the spindle L, provided with -a head,M, having a spiral end surface for acting on thev rounded end of thespindle, substantially as herein shown and described.

8. In a punch, the combination, with the block or frame A, of thesliding die E, the spindle L, having a squared head, L', and a head ornut, M, adapted to act on the die. the key S, fitting on thehead L', andthe handle S in the said key. substantially as herein shown anddescribed.

9. In a punch, the combination. with. the block or frame A, of thesliding die E, the spindle L, having a nut or head, M, adapted to act onthe die, the adjustable gage plate P, having a lug, P. the gage-plate Q,and the adjustable gage (MY on the saine, substantially as herein shownand described.
